what's that mean?
oh a side note, all round pinter's in the case of a zombie/robot apocalypse
A honeycomb bed allows the laser to disperse after it has annihilated what was placed in front of it. It also allows air to be circulated and extracted under the workpiece. A flat bed will simply get scorched, and most probably mark the material on the underside.
And yes I have welcomed out robot overlords, now I need to get the laser tube portable for the zombies. How can I create 20Kv on the move?
